idma64: Don't try to serve interrupts when device is powered off
[ Upstream commit 9140ce47872bfd89fca888c2f992faa51d20c2bc ]
When iDMA 64-bit device is powered off, the IRQ status register
is all 1:s. This is never happen in real case and signalling that
the device is simply powered off. Don't try to serve interrupts
that are not ours.
